ATG Europe has developed a one-shot manufacturing process for uninterrupted prepreg fibre-placed lattice structures that aim to replace current satellite central tube designs. These cylindrical lattice structures offer optimal structural functionality at a reduced mass.

This innovation included the design, development and manufacture of a fully representative CFRP lattice central tube based on requirements for ESA’s PLATO satellite, including all necessary interface zones. Thermoset pre-preg carbon fibre tows and patches were manually laid-up onto a mandrel, consolidated and cured in an autoclave in a single step to form one integral part. The primary interface to the launcher structure was provided by a one-piece aluminium interface ring, which was assembled to the lattice cylinder through a hybrid joint.

Key Benefits
• One-shot manufacturing process
• Structural efficiency and significant mass savings
• Uninterrupted pre-preg fibres leading to optimised structural performance
• High specific stiffness
• Reduced manufacturing time and cost
